SPECIFICATION forming part of Letters Patent No. 416,183, dated December 3, 1889.

Application filed January 5, 1889. Serial No. 295,519. (No model.)

To (0Z5 whom it may concern:

Be it known that I, ELIAS B. REQUA, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New J ersey, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

The invention relates to improvements in lamps, and particularly to the class of lamps described and claimed in Letters Patent of the United States No. 342,133, granted to me May 18, 1886, and 'Nos. 362,536 and 362,918, granted to me on the 10th day of May, 1887. The said lamps consist of an elevated reservoir and a burner-fount, the reservoir and fount being connected by a pipe which terminates at the lower end of the former and upper end of the fount, the end of the pipe in the reservoir beiug provided with a valve which may be operated by a valve and cup at the upper end of the reservoir, so that when the valve at the upper end of the reservoir is open the valve in the said pipe will close, and vice versa.

The present invention retates particularly to the construction of the burner; and it consists in the elements hereinafter described, and pointed out in the claims.

In the drawings forming a part of this specification the valve in'the upper end of the elevated reservoir is shown; but the details of construct-ion of the lower part of said reservoir are not shown, since they form no part of the invention, and their construction and operation are well known in the trade in addition to being illustrated and described in the patents above mentioned, particularly in the one numbered 362,536.

Figure 1 is a side elevation of a lamp embodying the elements of the invention, the burner, globe, and fount being in section and a portion of the reservoir being broken away. Fig. 2 is a detached side elevation, partly in section, of the inverted-cone-shaped button applied at the center of the burner; Fig. 3, an enlarged central vertical section of the burner, the section being on the dotted line X X of Fig. 6 Fig. at, a transverse section 011 the dot-ted line Y Y of Fig. 5; Fig. 5, a bottom view of the burnenbase; and Fig. 6 is a top view of said base, partly in section, with the upper portions thereof removed for the purpose of clearly disclosing the wheels by which the wicks may be raised and lowered.

In the drawings, A designates the stand for the lamp, B the oil-reservoir, and O the burner-fount, the reservoir and fount being connected by a pipe D, through which the oil may pass from the reservoir to said fount The invention sought to be'protected hereby refers particularly to the burner. Upon the upper end of the burner-fount C is screwed the sheet-1netal cylinder P, which extends upward a suitable distance and receives in its upper end the lower edges of the burnerbase Q, hereinafter specifically described. Within the cylinder 1 is supported the central tube R, having at its lower closed end a vent S, as shown more clearly in Figs. 4 and 6. The tube R is supported upon the inner ends of the transverse tubes T (shown clearly in Fig. 5,) which open at the sides of the cylinder 1 and form means for the admission of air to the central tube B, through which it passes upward to the flame. The upper end of the tube R terminates at the center of the burner-base Q, and is there eov-- ered by a foraminous cap V, which serves to thoroughly diffusethe draft passing upward through said tube. The outer ends of the transverse tubes T T are also covered with foraminous caps \V \V, which aid in thoroughly diffusingthe draft of air entering the central tube R. The upper edge of the cylinder P is provided with notchesad, as shown clearly in Fig. l, and the lower edge of the burner-base Q is provided with projections b I), also illustrated in Fig. l, which are of suitable size to snugly enter notches a, and pass beyond the same beneath the flange surrounding the upper edge of the cylinder P when the burner-base Q is turned, the purpose of the projections 12 and the notches a being to permit the locking of the burner-base upon the upper end of the cylinder P. The burnerbase Q is bowl-shaped and perforated, as illustrated in Figs. 1 and 3, and has surrounding its upper edge the right-angle flange d, forming a support for the outer edges of the foraminous plate 6 and the lower edges of the combined globe-support and flame-domef. At the center of the burner-base Q is supported the external tube g and the internal tube h, the latter being connected with the former by the partitions vi. (Shown in Figs. 4c and 6.) The tubes 9 h extend upward to the upper edge of the flame-dome f and form between them spaces for the wicks j, the wicks beingone on each side of the tube h and completely filling the spaces between the partitions 2'. At the base of the tube g are secured the housings m, as illustrated more clearly in Fig. 6, for the wick-raising wheels m, the latter being mounted upon shafts 0, one of which carries the button q, and all of said shafts being connected at their ends by.

the intermeshing pinion-wheels R, whereby when the button q is rotated all of the shaft-s, with their respective wick-wheelsn, may have a simultaneous movement. In the arrangement of the wick-wheels n illustratedin Fig. 6 the middle portion of each wick is held by two of the wick-raisin g wheels, while the adjoining edges of the wicks are held by the wick-wheels shown one on each side of the partitions i in Fig. 6. The object in thus arranging the wick-wh eels is to insure a uniform movement in the wicks, so that above the partitionst' the edges of the wick may meet, forming a cylinder, and each have a regular uniform movement, the upper edge of the cylinder formed by the two wicks being thus kept uniform. The partitions t' terminate about on a level with the center of the wick-raisin g wheels n, as indicated in Fig. 3. The flame-dome f has at its lower portions the flanges s t, the former of which carries the elevated rests u, (see Fig. 5,) and the latter receives the lower edge of the frame to, which retains the lower edge of the globe or chimney 0c in position. The frame to is simply slipped upon and closely hugs the lower portion of the flamedome f, and when in position permits the lower portion of the globe or chimney ac to pass between it and the flame-dome f and rest upon the globe-rests u, as illustrated in Fig.

' The central tube R contains a vertical partition l, which divides the currents of air passing through the trans-verse tubes T and insurest-heir movement upward through the foraminous cap V and inner tube 71/. If the central partition t were not provided, it is possible that the current of air would become disturbed and more or less irregular, owing to the fact that the air, to some extent at least, would pass directly through the cylinder P from one tube into the other instead of turning upward through the tube 7L. Upon the upper end of the partition 12 is secured the pin z, which receives the sleeve A and the lower end of the button B, the sleeve serving to support the button upon the upper end of said pin. The button 13 is constructed from perforated metal enameled on its inner and outer sides, the enamel completely covering said button and filling the perforations thereof, so that during the enameling process the material will become immovably fixed upon the button andavoid all liability of being cracked orchipped off when in use. The material on the outer side of the button being connected with the material on the inner side of the button by the ligaments within the apertures renders the article durable and not easily injured by ordinary use. This button is in the form of an inverted'cone, and the flame from the wicks 7' completely envelops it. The enamel on the button B will preferably be white, in order that it may increase the brilliancy and illuminating-power of the flame.

In the use of the lamp the oil is first poured through the valve E in the well-known manner into the reservoir B, after which by the closing of the valve E the inlet from the reservoir B to the pipe D is opened, whereby the oil will flow through the pipe D into the burner-fount O, whent-he lamp will be ready for use. \Vhen the lamp is lighted, the flame will be fed by the currents of air passing through the tubes T and B into the inner tube h, and also by the currents passing through the perforated burner-base Q and foraminous plate 6. In addition to the air thus supplied within the flame-dome f, a draft of air will be created around the lower edges of the chimney or globe as, this being permitted by reason of the globe being upon the elevated rests u. The air passing beneath the chimney or globepc will pass upward on the outer side of the flame-dome f and aid in rendering the flame regular and brilliant. It is essential that a Vent should be provided in the burner-fount C, in order that a vacuum may not be created therein, and hence I provide the vent S in the lower end of the central tube R and vent D, formed in the upper portion of the cylinder P.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. In a lamp, the cylinder P upon the upper end of the burner-fount O, the central vertical tube R, and transverse tubes T, supported by said cylinder, the tubes T extending from the tube B through the said cylinder, combined with the burner-base Q, attachable to the upper end of the cylinder P, and the wick-tubes g h, extending upward beyond the tube R and the flame-dome, substantially as and for the purposes set forth.

2. In a lamp, the wick-tubes and burnerbase, combined with the inverted-cone-shaped button 13, perforated and enameled on its inner and outer sides, the enamel filling the perforations, substantially as'and for the purposes set forth.
